Discover what 800 watts of reference-grade power can do at your next event.

The Avantone Pro CLA-400 Studio Reference Amplifier from Avantone is a dynamic, high output, high resolution, full-range system built the old school way; a classically designed Class A/B amplifier. Avantone took particular care to create an amplifier in the traditional studio style, with generous VU meters, high quality Japanese components and a serious toroidal transformer linear power supply. The CLA-400 implements a classic bipolar transistor design for robust bottom end. In a standard 3U rack mount chassis, this amplifier can generate over 360 watts per channel into an 8 ohm load, making it ideal for medium to large speakers in a studio environment. The CLA-400 not only uses no-compromise components, but is also convection cooled, which means there is no fan noise, so it can be used in the same room as the monitors. The CLA-400 Studio Reference Amplifier is designed to be used in a studio environment requiring high power output with no fan noise. Under testing, it delivers a powerful 400 watts into 8 ohms and can run at one third power without thermal fault. The CLA-400 has zero fan noise, as it’s convection cooled, which makes it well suited for control room installation.
